Looks like a very slow roll out. Only 8 cars in the last 2 days have received it according to teslafi. So far no 3 has received it, only S and X. Hopefully the 3 will get it also, I’m sure the performance version will need it too!
Great feature, they might as well call it teen driver mode, but it applies equally to loaning your car to in-laws, valet, or anyone who may not have the driving experience or be able to handle the power safely.
